We had four seniors on this trip so we booked a Cabana for the day. This is an excellent deal for a group. You get 8 beach towels so you don't have to bring any from the ship. Plus a fridge with 8 bottles of water, a bowl of fruit, chips and salsa and a $50.00 drink credit. There are four loungers and four chairs along with a large table which is all set with dishes. The only problems were that we were supposed to have a priority tender which didn't happen and it is a long walk to the cabanas. At least 10 minutes which is not easy in 90F heat. Plus there is a stairway to get to the cabana. The buffet was great and there is a shopping area (another walk). The only problem was that apparently there is a private shower behind the cabana and our guide never told us and we never thought to walk around the back of the building. Also if you are planning to snorkel NCL insists that you wear a snorkelling vest (even if you are an experienced diver) and you have to RENT them.
Overall I would recommend this as long as the walk would not bother you.
